specification of Letters Patent. Patente d June 26, 1917 Applicationfiled September 2, 1916. Serial No. 118,298.

I and State of Colorado, have invented a certain new anduseful'mprovement in Humidifiers for Gasolene-Engines, of which thefollowing is afull, clear, and exact description. j

My invention is an improvement in means for supplying water vapor to theexplosive mixture of gasolene engines and is particularly adapted foruse in connection with automobile engines. The objects of my inventionare; first, tok provide means for supj plying water vapor to the mixturejust sub sequent to carburization; second, to provide -automatic meansfor admitting -this water vapor in predeterminedquantities; third, to

provide means for adjusting the same humidier to operate in connectionwith en-` gines of various sizes; fourth, to provide meansA forcirculatingthe water from the water cooling vsystem ofthe engine throughthe device for generating thevapor to be used; and, fth, "toprovide-such a device lene engine it will operate automatically for.that when adjusted to any particular gasothat engine without furtheradjustment.

In the single l.view of the drawings accompanyingl lthis application Ihave illustrated my ,device as. Iapplied'to an automobile'engine, mydevice boing` shown inthe central.

vertical section and the automobile 'and its Acarbureter in brokensectional elevation.

Referring to the drawings, my device comprises an outer reservoir Athrough which the water of the cooling system circulates and an innerevaporating reservoir or chambei' -B which is in communication with thecarbureter of the engine. As shown in the .'drawings, the referencenumeral 1 indicates the wall. of the outer reservoir and 2 the wall ofthe inner one. Water is admitted to reservoir A through the pipe 3 whichis in communication with the lower water pipe 4 of the engine coolingsystem. Water entering through 3 passes through the reservoir A andescapes through the pipe 5 into the high or return pipe 6 of the coolingsystem.

The inner reservoir B has a port at its lowest point communicating withthe reservoir A, this port being controlled by a cone valve 7 operatedby the oat 8 within the `carbureter 16. Ifprefer reservoir` B. The stemof the valve 7 is continued axiallyabove the iioatS as shown at '9 andpasses out through theneck 10 which projects above the cover plate 17. Ascrew cap 11 closes the neck 10 and surrounds the enlarged head 12 ofthe stem 9. this head. 12 being of such size as not 'to be able to passthrough the neck 10. y

In the top of the reservoir B there is provided a port let adapted to becontrolled by a manually'oper'ated pin-valve 13.z The port 141 is in'communication with a pipe 1.3 which leads, as show finto the top of the,make the resern form withoutvoirs A and B cylindric( vvardly turned topflangesflSand 19and to.

support both these reservoirsby` connecting them to the top plateA 17 Yby nil/cans of bolts as shown, the top plate y17 being supported by anysuitable part of the engine structure. The parts should be so made thatthe joint between the iiange 19- andthe top 17 1s air-tight;consequently any suction setup through the port 17 will tend to producea vacuum in B. A

Operatz'on.

AThe heated water circulating through A,

and will tend to vaporize the water -inlB, this tendency being increasedbythe .diminished atmospheric pressure in B. Thesuction set up by theengine through the intake will draw any vapor so produced into the topof the carbureter through the pipe 15. The amount of vapor drawn` o iffrom B canbe conveniently regulated byy manipulating the valve 13 andwhen this is oncey set for a given engine substantially a uniform amountof vapor will be discharged inasmuch as the vaporization takes place ina secondary chamber, heated by the water system, the temperature ofwhich does not materially vary.

Wvhen the level of the water in reservoir B has fallen to such a. pointthat the water will not keep the float 8l insuspension the valve 7 opensand more water is admitted until the float rises to such a point as .to

close the valve 7 again.

valve T. The headlQ is larger than the neck 10 so as to prevent thetloat S from falling so low as to close the intake to B and thus preventwater entering B when the system is again filled.

IVhile I have described my device as a separate entity and thereforerequiring the provision of a reservoir Ait will be obvious that thisreservoir may be constituted by a pocket cast, or otherwise formed, onthe water jacket of the engine at any convenient point; or thatalportion of the radiator properly made may form this outer heatingchamber.

I Iaving thus described mv invention. what I claim and desire to securehvv Letters Patent is:

1. In combination with a water-cooled gas engine, a vaporizingreservoir. connections from said reservoir to the intake of said engine,aud means for circulating the cooling water of said engine around saidvaporizing reeervoir.
